Backfiring while Running

Have cub cadet, twin cylinder lawn tractor with only 60 hours on it. The engine has now started backfiring when
I speed up engine or putting under load such as switching on mower deck. Pulled plugs, one burning clean and light brown, other has some dry black build up. Engine not smoking. Any ideas??

Well, not knowing the year, engine make or any ID numbers of both the chassis and engine, I can only recommend installing new spark plugs and see what happens. That's like going to an automotive store and looking for parts for an F-150. They've been made since 1948 with countless engine options.
